OilSmart® Single Phase Duplex Panel Features

Industrial-Grade Automatic Oil-Water Pump Control – Engineered for Reliability

The OilSmart® Single Phase Duplex Panel provides automatic oil-water detection and pump control for industrial pits, sumps, vaults, and tanks. Designed to protect pumps, automate operation, and provide immediate alerts, this duplex system keeps facilities running efficiently with minimal oversight.

Design

UL-certified industrial construction: NEMA 4X rated for rugged reliability in pits, sumps, vaults, and tanks.
Two-pump smart control: Alternating and high-demand logic ensures both pumps operate efficiently without manual intervention.
Full alarm system included: Visual and audible alerts differentiate oil and water conditions, keeping operators immediately informed.
Plug-and-play simplicity: Pre-wired panel, sensors, and cords streamline installation for fast, compliant operation.
USA-built reliability: Engineered and tested to withstand harsh industrial environments.

PERFORMANCE

Automatic water pumping: Pumps water without pumping oil, reducing environmental risk and potential fines.
High reliability: Duplex logic ensures continuous operation, even under high water inflow conditions.
Advanced sensor integration: OilSmart, High Water Two Pump, and LiquidSMART Alarm sensors work together to protect pumps and alert personnel.
Minimized downtime: Immediate alerts for high water or oil conditions prevent costly system failures or environmental hazards.
Versatile industrial use: Ideal for pits, vaults, sumps, and tanks in manufacturing, chemical, and industrial facilities.

INSTALLATION & MAINTENANCE

Plug-and-play deployment: Pre-wired panel and sensors allow fast installation without complex electrical work.
Low maintenance: Only occasional inspection of pumps and sensors is needed.
Remote monitoring ready: Dry contacts allow integration with existing plant monitoring systems.
Compact, durable design: Heavy-duty NEMA 4X polycarbonate and Type 3R component enclosures protect against harsh conditions.

WHY OILSMART® SINGLE PHASE DUPLEX PANELS MATTER

OilSmart® Duplex Panels deliver automatic, reliable operation with minimal oversight. Designed to pump water while ignoring oil, the system protects pumps, reduces cleanup costs, and keeps industrial operations running smoothly. With built-in alarms, two-pump alternation, and high-demand logic, facilities stay protected and ready to operate immediately in any pit, sump, or tank environment.

Control Panel That Operates Two Pumps

The OilSMART Duplex Panel, when combined with two manual sump pumps, will automatically pump water without the risk of pumping oil into the environment. The panel provides pump alteration and high demand two pump operation. Additionally, the duplex system alerts maintenance or building personnel in the event of a high oil or high water condition. The control panel comes complete with all required controls and panel monitoring capabilities. Installation of Duplex allows you to comply with State and Federal regulations while reducing the risk of adverse publicity, fines and expensive cleanup costs.

Operation:

OilSMART Water Pump Switch

When water comes in contact with the short (on) sensor, the pump will turn on; The pump will remain on until water clears the long (off) sensor. If oil comes in contact with the on sensor, the pump will not turn on; however the pump switch will activate and pump water from under the oil. Oil does not harm the system in anyway. The sensors can oscillate through oil and see water.

High Water Two Pump Switch

If water continues to enter the sump and one pump cannot keep up with the inflow of water, water will make contact with the sensor of the High Water Two Pump Demand Switch. If water comes in contact with the sensor, the second pump will turn on and both pumps will continue to pump water until water clears off the sensor of the Oil Smart Switch, shutting both pumps down.

LiquidSMART Alarm Sensor

If a high Liquid comes in contact with the sensors of the LiquidSMART Alarm Sensor, the sensor will send a signal to the control panel that there is a high liquid present. Simultaneously, the alarm sensor will differentiate and indicate if oil or water is present.
